To all whom t magno/neem.'

Be it known that l, SYLVEs'ri-r. L. Gooiiix, a citizen et the United States, residing;- Boston, inthe county of Sullolk and State ot E'lassachusetts, have invented certain linproreinents in Machines 'for Inserting Fas! teners, unich the following description, in connection with the accompanying drawings, is a specication, like reference charneters on the drawings indicating like parts in the several figures.

Il'his invention relates to fastener inserting' n'iachine and is disclosed herein as cinlodied in an eyeleting machine equipped to insert blind and invisibleV eyelets in the niaini'liacture oft boots and shoes.

nA (tf Blind and invisible eyelets are ordinarily inserted in shoe uppers by a machine having a set provided with a clenching shoulder ot small diameter arranged Vto be inserted through a hole punched in one ot the layers ot the shoe upperito nieet the'enterinc; end ot' an eyelet barrel introduced from the other side ot the shoe upper. Thus the eyelet barrel is clenched between the layers o't the upper titer the layers have lbeen pernianenti ecured together and Without disturbing; uien' relation to one another.

.'llhis operation has been performed in the past both by machines haring` a separate punch and set operating; alternately as `-the Werl: Yted through the nnrchine and by machines having a conihined punch and set which tirst punches a hole in the shoe upper and later clenches the eyelet between 'the layers Without having' been withdrawn 'troni the hole in the upper. rlhe latter type of nie-chine has beconie Very Apopular for this operation and at the present tinie is ordinarily used tor it. lt in connection with the insertion o't invisible eyelets by a machine et this type that the present invention is dis losed.

J'orin the hole. Froinlthis it vfollows that after the eyelet is clenched inthe worltit adheres to the setting tool with `considerable teimcity.A Y'

lt is an objectot the presentinventionfto provide a stripper adapted to use inthe settingl ot blind und invisible-eyelets `and. arrangedte stripthe Werl; troni the setting tool after an eyelet has beenfelenched. -As herein disclos'ed,-tliis stripper'is carried by a port ot the inechine sepa-rale "troni "the setting tool, the stripper *and'settingl 'tool beingl relatively inovablesothatiinthe lcycle et operation'ot the nieeliine Ithe Vstripper inay positively clenched eyelet in it from the -setting tooly and is movable laterally in unison'with the Work, to facilitate the eedingaof tliework. As illustrated, this stripper member serves also as an abutment .toliniit the fin'oveinent o'l the Work pistV the setting' shoulder-ot'l the tool so 'thatthe eyelet may be 'relied'l upon to pass through .the layer upon which it is to be clenched. Vlhestripper is ar-V ranged te cooperate also with the coinplenien tary set which Vintroduces theV 'eyeletf` into setting position and servesV to apply clenchingg' pressure to theeyeletfso thatfaifter the prongs in the eyelet barrel havebeendeiected by the clenching` shoulder between the layers et the Work theywillbe further squeezed so as totlatten thein end'tigliten their hold upon the' Work. 'With thisebject in vView and also in order tosecure an etli-V cient stripging and work-positioningaction7 the stripper nieinber is illustrzte'des provided with a hole only as inuc'h largerthan the setting shoulder of thetoolnsiis necessary to provide a satisfactory Working' clearance.

ln orderthat the stripper may not-intertere with the punchingy operation otithe combined punch and set .and atf'the seineI While the invention is illustrated in con necticii with a right-side-up eyelet-set ting machine arranged to insert eyelets with Vtheir flanges uppermost, and while the invention is well adapted to such a machine,

it should be borne in mind that it is shown in connection with( that machine primarily for purposes of illustration, and that its utility is not 'limited to use in that connection since, evidently, in various of its as-r pects it may be used in connection with other Vtypes of machines.

W'itli the above and other objects andY features" in view, the invention will now Y the work-engaging instrumentalities and embodying one practical adaptation of the present invention; y

Fig. 9 represents a perspective view of a fragment of an article of worl'sucli as the quarter of a boot or shoe.

In order to avoid unnecessary drawing and description no attempt has been made to dis- Vclose herein'a complete eyeleting machine,A

but since the machine selected for' the purpose of showing one practical embodiment supplied to an inserting tool 10 by a raceway 11, the inserting tool being provided CDT with a springepressed spindle 12 arranged Y to pass through the barrel of the .leading Aeyelet 13 in the raceway and thereby to detaclithe eyelet from the raceway inconsequence of retracting the latter transversely of the axis of the spindle. f The in` serting toolis reciprocated endwise and its movement is guided by a stationary bearing 1e in the frame of the machine.

- The tubular clenching tool is provided with a clenching shoulder 15 of such form and arrangement that it is adapted togo through a layer of the work so as to perform its clenching function between two superposed layers, as shown by Figs. 6 and 7. This Vtool is provided with a hollow pilot portion 16 one function vof which is to guide the barrel-of the eyelet to the clenching shoulder and another function of which is to punch a hole in the work to receive the eyelet. For the latter purpose the'tool is formed with a central bore 17 through which the punchings pass, the end portion 16 being so thin, if not actually sharp, as to cut a hole in the work. In order to complete the punching equipment themachine is provided with a punch-bed or blocl18 which, as shown, is rigidly fastened' to a carrier 19. This carrier is provided with a shank-portion 20 and the latter is arranged to slide lengthwise in a bearing provided by a Ylaterally adjustable slide 21. n

The punch-bed and the inserting tool are separated laterally one from the other a distance corresponding to the desired spacing'- betweensuccessive eyelets in the work, and

the punching, feeding and clenching tool is accordingly. shifted laterally from Ythe puncli-bed t0 coaxial registration with the inserting tool for the purpose of feeding the worlafter having punched it and 'before the eyelet isinserted. The amplitude of lateral motion of the feeding tool will vary according to the desired spacing of eyelets, and the operating mechanism by which the feeding motion is imparted is regulat able for varying the extent of feeding moytion.

The feeding tool is arranged to slide endi.

wise relatively to a feed-carriage 22 the motion of which is guided by rods 23. The mechanism shown byFig. 8 for reciprocating the feed-carriage includes an oscillatory arni 24, a roclshaft 25, an arm 26 aflixed to the rockshaft', transmission links 27y and 28 Cil pivotally connected one to the other by a, pin 29, a linlr 3() arranged to constrain the movement of pivot 29 to a segmental path, and suitable means (not shown) for imparting longitudinal reciprocation of uniform amplitude to the link 28. The arm 24 is oscillated by the roclrshaft- 25 but is connected to the latter by an adjustable connection indicated as a Whole at 31 and of such construction and arrangement as to provide for angular adjustment of the arm relatively to the rockshaft. The outer end of the arm is forket and embraces a block 82 that is carried by the feed-carriage and connected thereto by a pivot member 33. The construction and arrangement of the mechanism is such that he lett-hand limit of motion of the feeding tool is in every case coincidental to the axis of the inserting tool 10 whereas the rightliand limit of motionv is variable according to the amplitude of spacing for which the mechanism is regulated. Such regulating is eifected by varying the location of the pivot member 3l to which the link 30 is anchored. As shown, the anchoringpivot 3l is carried by an oscillatory regulator arranged to oscillate about a stationary pivot member 36. The regulator is provided with a handle 37 that overlies a stationary plate 38 in which numerous holes 39 are formed for the reception of a stop-pin -l-(l. Se long as the regulator remains in one position the amplitude of feeding motion will remain constant but whenever the regulator is swung' to a new position the change of location thereby effected with respect to the anchoring pivot Bel amplilies or decreases, as the case may be,

the extent of motion transmitted to the fee'dcarriage. i

The regulator also serves to effect a corresponding change in the location of the punch-bed 18 so that the latter will be spaced from the axis of the inserting tool according to the amplitude of lateral motion to be imparted to the feeding tool. For this purpose the regulatorV is provided with a cam-slot a This slot is occupied by a camroll 42 carried by a lever e3, the pivot member of which is indicated'at 441;. A universal joint of suitable constiuction7 indicated as a whole at 45, forms connection between the lever 4:3 and the slide 21.

Although the drawings do not include any means for controlling the holder 19 with respect to movement toward and from the worl-, any suitable means such as that shown in the aforesaid Patent 133427238 may be provided for sustaining the holder rigidly against the punching stress executed by the punching tool 16.

stationary work-table is provided for snp-porting the work in co-o'peratiif'e relation to the several tools, said table comprising` an elevated 'work-engaging.;` portion il@ and having a slet l? extending.- parallel to the lines of feeding motion-to receive the feeding` tool and to receive a fla-t work-sustaining member 48. The holder 191carres also a` presserfoot 50, the latter being` movable toward and from the Work-table relatively to the holder and, being'- guided in such movement by confronting portions-v51 of the holder between'which the shank'por-v Y tions of the presserfoot are arranged to slide. Preferably the holder 19 is bored for thereception of acompression spring, as shown in the aforesaid patent9 the function of said spring einig'V to maintain a downwardpressure on the presserfoot so' that 'the latter willv function continuously in conjunction with the' work-table to clamp the worlr.

The specimen of work illustrated comprises a plurality of superposed la'yersQ, and of which the bottom layer would be the outside ofthe upper in the case of invisible eyeleting` and of whichv the top layer would be the outside of the upper in the case of blind eyeleting. he other layers would be the lining and the eyelet-stay. `11n some shoes the lining may be interposed between the eyelet-stay and the upper while in others the eyelet-stay may be interposed between the lining and the upper.

Thepunching, feedingl and clenchin'g' tool is attire-d to and carried'by a holder 55 and the latter is arranged to slide -endwise in -a bearing afforded by the feed-carriage 22. Any suitable mechanism mayv be provided for reciprocating the holder7 the mechanism shown including toggle members 56 and 57, and a connecting rod 58 arranged'to operate them. rlfhe member 5T is mountedv upon a stationary pivot member 59, The joint connectingthertwo toggle members and the rod 5S is formed by a pivot member'll.- The connecoion between toggle member 56 and the. holder is formed by a pivot memberv G1, andthe atter is elongated so that it may maintain operative connection with "the holder without requiring the toggleniembers to partake of the feeding notion.

The elements thus far described operate as follows: Starting from the positionshown by Figs. 1 and 2, which represent the initial positions of the several instrumentalities, the punching tool rises until it enlgages the punch-bed 18 as shown by F 3, thus punching' a hole through all the layers of the work.V In most cases the punching operation would result in passing'the clencli- I ing shoulder 15 partway if not entirely through the lower layer 52 but this would obviously not be the case if the aggregate thickness of the layers were less than the distance between the clenchingg` shoulder and the upper end of the punching tool. 'The pivot member G0 is carried past dead center as a continuation of its punching-v motion, thereby retractingr the elenc'liing' Vshoulder 15 to the critical position, relatively to the member 48, for clenehing the eyelet. `This refractory'inotion may be, and preferably would be slight, so as to avoid withdrawing the pilot portion from the work. Furthermore itV relieves the pressure of the punch against the punch-bed before the tool moves laterally. From the position shown by Fig. 3 the punching tool moves from right to left for the purpose of feeding the work froin the punching locality to the eyelet-setting locality where the punching tool will occupy the position shown by Fig. 4.' l/Vhile the punching and feeding motions are'occurring-the inserting tool lO will descend andthe raceway will-be retracted so that'an eyelet will Vbe taken from `wardly by the clenching shoulder l5,

shown by Fig. 6, and ultimately clenched as shown by 7, after which the setting tools will be retracted yto their initial'levels and the clencliiiigptool will also be shifted laterally to its initial position as shown by Fig. 2.

During the operation of inserting the barrel of the eyelet through fthe layers 54 and A53 the tendencyof the eyelet is to force the work toward and past the clenching shoulder, the tendency varying according to the density andV thickness of the work. In some cases the resistance offered by the eyelet-receiving material to the passage'of the eyelet therethrough is so great that one or` both of said layers Vwould be pushed beyond lthe clenching shoulder if some means werenot provided for arresting them against the stresseXerted by the eyelet.

work at a position relatively to the clenching tool such that the clenching shoulder will lie between-ther two layers where it is desired to have the clenched portions of the eyelet lie. Accordingly, means is provided for insuring that relation between the work and the clenehing shoulder, regardless of vvariations in the physical properties and thickness of the several elements comprised in the work. ln the illustrated embodiment of the invention the member 48 accomplishes this result.V This member as shown is supported independentlyV of orotherwise than by the tool-holder 55 and is therefore capableV of functioning more Yeffectively than it couldif it were carried by the' latter. It is,fvliowever. preferably movableY laterally in unison with the clenching tool so that it will always occupy the desiied Y relation y Successful re-V sults require, in every case, sustaining the thereto. ,Asshowm it is fastened to and carried by the feed-carriage 22 audits connection with the carriage is preferably such as to make it rigid with respect to its several functions. As shown by Fig. l the feedcarriage is provided withk a groovein which v the shank portion of the member 48 isfitted. A set screw 68 is carried by the carriage and has a tapered end arranged to engage theV lower end of the member 48 to adjust the latter vertically.

A clamping screw 65er;-

tends through aV slot' 66 in the shank of the Y member 48 and has screw-threaded connection with the feed-carriage so that the head of the screw will bind the shank securely to the carriage when the screw is set up tightly. The member 48 will preferably be adjusted so that its upper surface will be below the work-sustaining surface of the table 4G to avoid friction with Athe work and the tendency to shift the work in the wrong direction when the feed-carriage is moving in the direction opposite toits feeding motion. On the other hand the distance between the top of the member 48 and the work-supporting` surface of the table 46 is preferably very slight in order to avoid appreciable distortion of that portion of the work that .bridges across the slot 47 in the work table,l

since, during the operation of inserting the barrel of the eyelet into the work, the downward pressure'o-f the eyelet on the work depresses the bridging portion of the wei-k. Although the member 48 is shown as embodying an L-shape, its proportions are such thatit is, to alll intents and purposes, rigid with respect to its effects onY the work. The overhanging portion ofthe member 48 is preferably smooth and flat in order to avoid marking the work, and is provided Ywith a hole 67 through which the clcnching tool passes in order to co-operate first with the punch-bed and afterward with the inserting tool. The rim ofthe hole is preferably rounded in order to avoid scoring the layer V 52. Although the bottom layer 52 of the'v work may not have been pushed beyond the setting' shoulder `incidentally to punching a' hole through the workit will be pushed past said shoulder by the eyeletA while the leading end of the latter is exerting downward pressure on the vlayer 54, As soon, however, as the bottom layer encounters the work-sustaining member 48 the downward movement of the work will Vbe arrested and tively to the tool, will remain stationary while the eyelet is forced through the layers 54, 53, the-layer 53 remaining above the cleiiching shoulder while layer V54 is below iis' ` iie thereafter the work, instead of moving relathe shoulder.V The leading end of the eyelet,

on encountering the clenching` shouldeixis 'turned outwardly as shown by Fig. 6, and

as the inserting tool continues to descend the leading end of the'barrel spreads radially between the layers 53and 52. As the leading end ol the eyelet moves away -trom the setting shoulder it.v lies on the upper surface ot' the. layer 52 which continues to be sustained by the member 4S, and at the moment when the clenching is completed the clenched portion is subjected to a pressure caused conjointly by the insertingtool and the member 48 within the area covered by the clenched portion. In this respect the member 48 is supplemental to the clenching shoulder l5 in determining the ultimate form olthe clenched portion, and the latter is flattened more than it would be in the absence of the sustaining action of the member 4S. y This feature is advantageous since it reduces the lump caused bythe presence of the clenched portionbetween the layers, and furthermore it secures the eyelet more firmly in the work so thatthe likelihood of subsequent loosening oitthe eyelet due to the pulling ot a lacing will be minimized. ln order to oppose the tendency of the eyelet to tilt when subjected to the pulling stresses of` the lacing it has been customary to .provide the eyelet with a relatively broad flange 68, but for some kinds of shoes the manufacturers prefer a relatively narrow and inconspicuous iiange. The supplementary ettect of the member 48, whereby the clenched portion of the eyelet is lattened after it has been curved by the shoulder 15, renders the clenched portion adequate to overcome the tendency of the eyelet to tilt and loosencand therefore permits the use of an eyelet thathas a relatively narrow liange 68.

t is to be observedA that the member 4S' does not partake ot the endwise motion of the clenching tool and consequently when the tool is retracted'after having completed the eyelet-setting operation the member 48, still sustaining the work, strips the latter `from the clenching/tool.

From the foregoing it will be seen that the member 48 vperforms three distinct functions: First, it insures the desired position oit the clenching shoulderb'etween two layers of the work.; secondit flattens and tightens the clenched portions of the eyelet that have passed beyond the setting shoulder; and third, it strips the work from the clenching tool as the latter is retracted. lt is also to be observed that since the member LS is carriedby the feed-carriage independently of the clenching` tool it willl partake automatically of variations in the amplitude oit' feeding motion so that it. will always remain in registration with the clenching tool and at the same time' be independent of all motions of the clenchingvtool lengthwise of its axis.

vin adjusting the severa-l work-engaging elements the preferred procedure would be as follows: First, toadjust: the punch and punch-block so that their conjoint operation will havethe desired result, then to adjust the inserting tool with regard tothe thickness of the work in which the. eyelets are to be set, and to, adjust the abutment, as ott-en as may be necessary, according to the thickness ofthe layer that lies between it and the clenching shoulder at themoment otclenching. The foregoing order of procedure may be varied according to circumstances.
